1).Carbon fiber heating plate due to uneven heating, with the same area of carbon carstal heating plate, the carbon fiber need increase the power to achieve the whole plate heating. In this way, the temperature difference is very big in the surface. The temperature overheating in the surface can cause the burnt block, like the sunspots gradually burnt cause damage and can’t heat up. to get more warmer,the carbon fiber plate cost more electricity.

2). The carbon crystal heating plate is even heating and the temperature difference of the surface is not big. with the same area of carbon fiber, the carbon crystal panel heater need less power to achieve the same effect of carbon fiber. The designed temperature of carbon crystal is 45-80 degree and no overheating point, let alone the burnt block.
